Some one suggested take a little off the very top of the cocking ramp right before the pin seats. Is this accurate?

The sear does triple duty. It holds the firing pin until the trigger releases it, acts as the bolt stop and bolt release. The "release" you press is an extended part of it.

The sear torsion spring has zero effect on bolt lift and only marginal effect closing and locking it to battery. It's sole purpose is to reset the sear to it home position opening the bolt.

Taking a little off the transition point between the ramp and retention detent only reduces the "click" at the end of the bolt lift. At times its "pointed" making the transition a bit on the abrupt side. It can be shaped to a radius to smooth out the transition. How much? I use a diamond stone to round the very tip to maybe a 1/32" radius at the most, nothing more, just enough to break the edge.
